Another Gene Found That Increases Risk of Atrial Fibrillation and Stroke

We continue to learn more about the family connection in atrial fibrillation. A second gene was just found that increases the risk of afib and stroke.

At least one third of those of European descent carry one copy of the newly-discovered variant in the ZFHX3 gene and have a 20% increase in risk of afib and cardioembolic strokes, those that originate from clots from the heart.

These findings will be integrated into DNA testing for atrial fibrillation and stroke risk from deCODE Genetics.
